when you do have the option of determinism, but intentionally eschew it in favour of a strictly inferior nondeterministic tool, then yes, it is kinda dumb.
What deterministic option are you referring to here? Humans certainly are not deterministic in how they interpret instructions and write code. If I asked you to implement a feature and a month later asked you to implement the exact same feature, you likely wouldn’t do it the same way again. Two different people certainly wouldn’t.
strictly inferior != bad. It's relative. One tool will still give the output i intended long after I'm dead and decomposed, with the other might not at the very next time i run it.
